Embodiment 1

[0044] First take 0.20 parts of silicon (silicon is added in the form of aluminum-silicon master alloy, Si content is about 11-12%), 0.46 parts of magnesium (magnesium is added in magnesium ingot, Mg content ≥ 99%), and the balance is aluminum (aluminum is Aluminum ingots are added, and the Al content is greater than or equal to 99.7%) for use.

[0045] It is then melted and refined.

[0046] Put aluminum and silicon into the melting furnace and heat it to 740-760°C, press magnesium into the aluminum melt with a magnesium cover to melt these raw materials, and then carry out the first refining in the melting furnace, add refining agent, remove The gas is argon, and the slag is removed after refining. Preheat the melt to above 800°C and transfer it to the holding furnace for the second refining, refining temperature: 740°C, refining time: 25Min, refining agent dosage: 1.5Kg / T, high-purity argon (content: ≥99.999% ) outgassing. Then carry out the third refining, and the refin...

Abstract

The present invention is a kind of aluminum alloy pipe for making photosensitive drum and belongs to the field of non-ferrous metal pipe manufacture. The aluminum alloy pipe is made of material comprising Si 0.20-0.23 weight portion, Mg 0.45-0.50 weight portion, Fe 0.01-0.15 weight portion, impurity elements S and P 0.00-0.01 weight portion and Al 99.34-99.11 weight portions. It is produced through smelting, refining, in-situ fining, in-situ deairing, filtering, casting to form ingot, annealing, heating ingot to peel, extruding breakdown, quenching, finishing, drawing, post-finishing and other steps. The aluminum alloy pipe has low impurity content, and is suitable for manufacturing high purity and high precision photosensitive drum and similar products.

Description

【Technical field】: [0001] The invention relates to a high-purity and high-precision aluminum alloy pipe material for photosensitive drum substrates and a manufacturing method, which belongs to the manufacturing industry of special nonferrous metal pipe materials. 【technical background】: [0002] OPC is an abbreviation for Organic Photoconductor. OPC drum is a photoelectric conversion device formed by coating the surface of conductive precision aluminum tube with OPC material. It is the core component of laser printers and digital copiers. There are high requirements on the surface and dimensional accuracy of the aluminum alloy tube material before coating: the removal rate of impurities above 5 μm in the microstructure of the final product is greater than 98%, while the diameter of impurities or metal compounds in products without special treatment is generally 20 μm about. The required tolerance of the outer diameter of the pipe is ±0.05mm, and the required tolerance of t...
